Medicaid work

$78,583 in 2018

Medicaid paid $78,583 for 1,037 billed services this clinician did in 2018, up to 121 people in a month for one service.

Medicaid and CHIP claims where this clinician did the service, fee-for-service and managed care together. Any month with fewer than 11 patients is hidden, so small Medicaid practices undercount.

Drugs they prescribed that Part D paid

$125,929

Pharmacies billed $125,929 in 2024.

This is pharmacy cost, not the office bill, and not what patients paid.

Opioids were 2% of their Part D prescriptions (24 of 1,413) in 2024. At or below the middle of the specialty; the typical family practice clinician is at 2%.

1,274 generic and fewer than 11 brand-name prescriptions · $125,929 in drug cost · 50 antibiotic prescriptions to 38 people.

Part D prescriptions only. The opioid rate is opioid prescriptions as a share of all this clinician's Part D prescriptions; surgeons and pain specialists run higher than others, so it is shown against the same specialty.
